Government official: Currently many business travelers rely on a one-hour flight between the cities, but complain about congestion and delays at the airport. The new high-speed railway between Hamport and Dudley, Aplandia`s two major financial hubs, will be able to make the same trip in slightly less than three hours. Given this option, many who fly between the two cities during the week will choose the railway, since it will allow them to travel between the city centers in less time than a flight with the expected delays plus the commute to and from airports would take.

Which of the following, if true, would most cast doubt on his proposal above?

【选项】Tickets in the first class of the high speed railway will be as expensive as the average price of a plane ticket.
